Claims (10)

Both an optical disk having a plurality of recording units in which information can be freely rewritten and an optical disk with a recording protection function having the same format as the above-mentioned optical disk and having information on address information in a different range and having a limit on rewriting or additional writing can be used. handling There, an optical recording apparatus characterized by not perform a write operation with respect to the recording protection with optical disk end information is recorded. 2. The optical recording apparatus according to claim 1, wherein the optical recording apparatus has an address detection circuit for the loaded optical disk and an address conversion circuit for processing a signal from the address detection circuit. 3. The optical recording apparatus according to claim 1, wherein the address conversion circuit performs a process of arithmetically operating a constant value from a signal from the address detection circuit when the medium with the recording protection function is loaded. . 4. The optical recording apparatus according to claim 3, wherein the arithmetic operation is a subtraction. The optical recording device further includes a control unit, the control unit receives an information recording instruction from a user or a higher-level device, and records the information in the recording unit area of the medium with a recording protection function. A reproduction operation is performed on the area, and if there is user information, the recording is stopped. If there is no user information, an overwrite prevention function that operates to perform recording on the recording unit area is controlled. 5. The optical recording apparatus according to claim 1, wherein: Claim the recording protection with optical disk, which has information for distinguishing the above rewritable optical disk control during control information area, and further comprising means for reproducing the control information region when the optical disk loaded 6. The optical recording device according to any one of 1 to 5. 7. The optical disk with a recording protection function according to claim 1, wherein the optical disk has an error correction block extending over a plurality of sectors, and does not process a recording instruction from a user or a higher-level device for a unit smaller than the error correction block. The optical recording device according to any one of the above. And rewriting non plurality of address information, identified by the address information, the same as the physical format of a standard optical disc having a plurality of recording unit regions rewritable, the range of address information to be subjected to a plurality of recording unit regions above Unlike standard optical disc, such write operation is not performed, the recording protection with optical disc, wherein the end information has been recorded. 9. The optical disk according to claim 8, wherein the address information of the optical disk with the recording protection function is obtained by arithmetically operating a constant value on the address information of the standard optical disk. 10. The optical disc according to claim 8, wherein information for distinguishing from the rewritable optical disc is included in a control information area.
